,This pedigree chart tracks the inheritance of a recessive trait that is not sex-linked. Based on the information in the chart, which of the following statements is true? A Individual #11 must be homozygous for the recessive trait. B Individuals #3 and #4 must be heterozygous for the trait. C Individual #2 must be heterozygous dominant for the trait. D Individual #9 must be homozygous dominant for the trait
here is the chart i am not understanding
May you clarify what about the chart is confusing you? Btw, just as a reminder. A heterozygous individual = has 2 alleles of one trait; one of which codes for a dominant expression and one of which codes for a recessive expression A homozygous individual = has 2 alleles of one trait; both code for either dominant expression or recessive expression The chart is based on phenotypes not genotypes. Based on it, a heterozygous individual would have an empty shape; a homozygous dominant individual would have an empty shape, and a homozygous recessive individual would have a shaded shape.
